Patent GB-1035935-A (GB)
Title: Improvements in or relating to apparatus for crimping yarn
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/12
Filed: 1962-04-04
Abstract: In a compressive-crimping apparatus, heated yarn 10 is forced through an arcuate grooved passage 24, 39, (in a heated element 23) against the restriction of the serrated periphery of a rotating wheel 25 so that it is compressed along its length to form a plug of crimped yarn moving with the wheel.  Yarn is withdrawn from the end of the passage 39 and through or over a heater 81 by winding mechanism 46 the speed of the friction roller 55 of which (also of nip rollers 9 and traversing yarn guide 62) is correctively adjusted i.e. periodically operated, so that the position of the head of the plug is maintained between acceptable limits and the level of the mass of crimped yarn (and, therefore, the crimping pressure) in the passage remains constant. Adjustment is effected in response to control initiated by a sensing device which does not restrict movement of the plug and is independent of the wheel and its function.  Such device comprises a forked blade 41 projecting through a slot 40 into the passage (through which slot the crimped yarn is withdrawn between the blade and the plug head) and operating a mercury switch 47 through an adjustably loaded, cranked lever 42: alternatively, one or more light sources project light through the passage and on to photo-electric cells on opposite sides of the path of travel of the plug head so that any change in the output of the cells arising from interruption of the light path by the plug head actuates control mechanism electromagnetically.  Figs. 2-4 (not shown).  The control is effected by change-speed gear embodying an electric clutch 49, 50.

Title: Burner for heavy oil
IPC: F23C99/00
Filed: 1926-05-25
Abstract: 252,400. Sambuc, E., and Brazzola, L. May 25, 1926. Porous block and spray burners.-A heavy oil burner comprises a refractory nozzle or firepot 1 formed with a reverberatory axial conduit which is fitted with a porous refractory hearth 2. The surface of the hearth 2 and bottom of the conduit are grooved so as to form projections or knobs 3. The axial conduit is slightly inclined and curved towards its outlet. Fuel oil is delivered by a pipe 4 on to the hearth 2 and burns initially under the influence of a weak air current supplied by a pipe 5. As the nozzle becomes heated the oil is vaporized more rapidly and the supplies of oil and air may be increased. Unvaporized oil is drawn off by means of a pipe 6. An air space may be left between the nozzle and its metal casing 7. The nozzle may have a sinuous or helical extension.

Patent GB-132774-A (GB)
IPC: D05B35/02
Abstract: 132,774. Stõubli, Geb. Sept. 16, 1918, [Convention date]. Book-stitching machines; knot-tying devices. - Sheets are stitched together by a single thread passed through one end hole of three, the upper and lower portions having a lock-stitch concatenation at the middle hole and the ends secured with a reef knot at the third hole. Labels are stringed by a thread passed round the edge of the label and having its ends knotted in the hole of the label. An eyed needle 79, Fig. 12, carries a thread through the first hole, and its loop is carried by a looper 29 past the second hole, where one arm is drawn downwards by a barbed needle 80. On the descent of the eyed needle, the thread between it and the work is engaged by a threepronged looper 14 and carried through the thread loop on the needle 80. Between the latter loop and the looper prongs, the loop upon the prongs is engaged by the V-shaped mouth of a part 122 which forces the two arms of the loop together. At the same time a pair of shears 16a, acting as a knotting-post, passes between the looper 14 and its loop, and, by a rotational movement about their eccentric support, the shears move the loop laterally. A hooked looper 112 then moves towards the left, Fig. 12, entering the loop on the prongs, passes between the looper 14 and the shears 16<a>, and engages the two arms of the loop drawn together by the part 122. The looper 112 then retreats, drawing a double loop 164, Fig. 14, through the loop on the prongs. The looper 14 is then withdrawn, leaving the thread looped around the shears. The second hooked needle 81 passes through loop 164 and the sheets and draws down the end of the thread from above the work through the loop 164, which is at that time held upon the underside of the work plate by a " knotter " 102. The shears are withdrawn to release the under portion of the thread, and a pair of tongs engages the supply arm of the under loop to draw the concatenation at the last hole into a tight reef knot. The shears again rise in open condition and are closed upon the supply arm of the thread close to the knot. During the stitching, the thread loop is held above the work-plate by means of slotted tongues which are moved across the long slot in the work-plate which extend from the first needle position to the third. On completion, the tongues are removed and the thread released. The tor.gues also support the sheets during perforation by the needles. When a label is being stringed, the eyed needle and the second of the hooked needles only are used. The thread is tied round the tongues on the workplate and forms a loose loop when the tongues release it. Simple cam mechanisms for operating the stitching-implements are described.

Abstract: 579,283. Explosives. WRIGHT, H. R., TAYLOR, J., and IMPERIAL ,CHEMICAL INDUSTRIES, Ltd. Aug. 18, 1943, No. 13426. [Class 9 (ii)] Aggregates containing crystals of pentaerythritol tetranitrate or other high explosive compound sensitive to detonation by friction or shock and nitrocellulose which has been gelatinized by a solvent are made as follows . The crystals of tetranitrate (or, it may be, of cyclotrimethylene trinitramine) and the nitrocellulose, both in water-wet condition, are made into a slurry with cold water. To the slurry is added a liquid solvent for the nitrocellulose, the amount added being insufficient to form a continuous phase, but sufficient to agglomerate the crystals and the nitrocellulose into discrete aggregates each containing the nitrocellulose (in swollen but incompletely-gelatinized condition) and a plurality of crystals ; the solvent used is substantially non - volatile, waterinsoluble and relatively insensitive to friction or shock, and may be explosive (e.g. a liquid mixture of dinitrotoluenes and trinitrotoluenes) or non-explosive or a mixture of both (e.g. dinitrotoluenes and trinitrotoluenes with dibutyl phthalate). The aggregates are separated from the bulk of the cold water without the application of any appreciable pressure, and dried, e.g. by hot air, without causing any substantial coalescence thereof. The aggregates are cooled and bagged and may be mixed (alone or with more nitrocellulose solvent which may be different from the solvent used to form the aggregates) until it becomes plastic, whereupon it may be extruded or loaded into containers. Specification 579,275 is referred to.

Filed: 1917-09-19
Abstract: 115,573. Justice, P. M., (Pirani, S. G.). Sept. 19. 1917. Hydrocarbons, cracking; bulk evaporators. -Light paraffin oils and other oils for motors are obtained from shale, and benzene, toluene, and solvent naphtha are obtained from coal by a process in which the coal or shale is heated with a mixture of finely ground carbonate or the like which under the action of heat gives off carbonic acid, and with small iron scrap or its equivalent which is adapted to increase the volume of hydrocarbons evolved. The temperature of the retort is maintained between 175‹ C. and 800‹ C. The produced oil is condensed and purified by fractional distillation, and the residuum from the still may be treated with carbonate and iron as in the first stage of the process, and the distillate therefrom passed to a second retort containing manganese dioxide and iron scrap preferably in the proportion of one part to two, in which it is further distilled. The still is of the construction shown in Fig. 8 and is fitted with burners 38, and with pipes 42 for the removal of residuum. The retort 1, Fig. 1, is heated by burners 13 supplied with producer gas, and is charged by means of belts and a overhead skip 5. The hopper 2 forming the top of the retort is fitted with a detachable lid 3.

Title: Improvements in or relating to apparatus for feeding solid fuel to furnace grates
IPC: F23K3/16
Filed: 1955-05-11
Abstract: 807,758. Stoker apparatus. INTERNATIONAL COMBUSTION (HOLDINGS) Ltd., and WRAY, J. W. May 11, 1955, No. 13682/55. Class 51 (1). In a furnace, solid fuel is deposited on a travelling grate by gaseous jets comprising admixed air and combustion products, the latter having been withdrawn from the furnace chamber above the grate. In the furnace shown, solid fuel from hoppers 8 drops, under feeder control 9, into chambers 7, each of which accommodates a nozzle 10. In operation, air from a main 11 issuing from each nozzle simultaneously feeds the fuel in its associated chamber down a conduit 12 to the furnace grate and induces combustion products to pass from the furnace to the chamber through a duct 6 for admixture therewith. Each conduit 12 is curved at 13 to direct fuel in a trajectory over the grate and variation of this trajectory is effected by operating a damper 14 in the associated duct 6 and a damper (not shown) between the nozzle 10 and supply main 11. Systematic and/or regular variation of either or both sets of dampers in ducts 6 and associated with nozzles 10 is achieved by coupling to mechanisms driven, e.g., by the grate drive, which impart to the dampers a required movement. Velocity variation of the air from each nozzle 10 may also be used to produce variation of its associated fuel trajectory. This may be achieved by using a fan with a variable-speed drive to supply the main 11. The nozzles 10 may be replaced by fan means.
